Help Vertical line in front camera

[frankiebi]

I have a white vertical line on the back camera of my new Nexus us I9020.
There is no line for the front camera and I've tried taking a photo with Instagram and other camera apps but the white line still appears.
Here's a sample photo I took to show you https://twitter.com/#!/FrankieBi/media/slideshow?url=http://instagr.am/p/J3s2nsAfvj/

Any ideas if this is hardware or software?

Thanks
